[The chemical composition and biological activity of the glyco polymers in Ralstonia solanacearum (Yabuchi et al., 1995)].
Lipopolysaccharide and extracellular glyco polymers were isolated from cells of phytopathogenic bacteria Ralstonia solanacearum. It was established that the O-specific polysaccharides are characterized by a linear structure, composed of tetrasaccharide repeating units containing three L-rhamnose residues and one of N-acetylglucosamine residue. Core oligosaccharide along with typical monosaccharides such as rhamnose, glucose, heptose, KDO and glucosamine included fucose, galactose and arabinose. Serological activity of lipopolysaccharide is due to both O-specific polysaccharide and lipid A component. Extracellular glyco polymers contained both neutral (GP 1) and charged (GP 2 and GP 3) components. Rhamnose and glucose (GP 1, GP 2) or galactose (GP 3) were predominant monosaccharides, GP 2 displayed a high phytotoxic action in respect to tomato plants.
